Some corkers right there. Started getting anxious about nothing from Porsche, until the 4.0 litre towards the bottom, I'm glad they went back to the larger, awesome sounding engines, emission standards can wait.
Only one I'd disagree with is Mazdas skyactiv, for a 2.0 litre, it's just too underpowered by modern standards, power doesn't have to replace economy as many a small displacement turbocharged modern units have proven...
